Chaque unité d'antenne quasi-Yagi comprend une structure de symétriseur électriquement connectée à un canal de radiofréquence du ou des canaux de radiofréquence, un réseau actif connecté électriquement à la structure de symétriseur, et au moins un réseau passif situé sur un côté du réseau actif et éloigné de la structure de symétriseur. Une bande passante de travail du réseau d'antennes quasi-Yagi est étendue au moyen de la formation du réseau d'antennes quasi-Yagi de manière empilée et dans un réseau, qui facilite l'intégration d'une antenne et des cartes de fréquence radio, réduit la taille d'un appareil de station de base, améliore le gain d'antenne du réseau d'antennes quasi-Yagi et réduit la perte de transmission. Une caractéristique large bande de l'unité d'antenne quasi-Yagi est réalisée par ajout de la structure de symétriseur pour réaliser la conversion du déséquilibre à l'équilibre.
